Good meeting for me tonight, thanks to all. I like the idea of an LCD television for the S-Video (chroma/luma) connection for the C64 40 column mode. I'll see what I can find for CGA/80 column adapters.
Based on our conversation I realize I should have a Vic-20 and an Amiga 500 in my collection, now that I have room to set it up. (I did have an A500, but I gave it away. Not sure where it went...) If there are any around in boxes gathering dust, I'd like to offer them a place to roost.
When the Covid thing is all over, I'll have to have you out for a Lemmings/Jumpman game night.
